JS方法

報(bào)異常如下

Error Domain=WKErrorDomain Code=4 "發(fā)生JavaScript異常" UserInfo={WKJavaScriptExceptionLineNumber=1, WKJavaScriptExceptionMessage=ReferenceError: Can't find variable: onFaceRealName, WKJavaScriptExceptionColumnNumber=52, WKJavaScriptExceptionSourceURL=http://12.12.12/verify/idcard-info.html?token=11292803131658321891878number2&s=1658374061429, NSLocalizedDescription=發(fā)生JavaScript異常}

OC調(diào)用JS方法

1.沒問題?

[webview evaluateJavaScript:@"app.onFaceRealName(123)" completionHandler:^(id _Nullable result, NSError * _Nullable error) {}];

2.沒問題?

??[webview evaluateJavaScript:@"app.onFaceRealName('123')" completionHandler:^(id _Nullable result, NSError * _Nullable error) {}];

3.有問題

[webview evaluateJavaScript:@"app.onFaceRealName(uid11292803112345946uuid)" completionHandler:^(id _Nullable result, NSError * _Nullable error) {}];

4.沒問題

[webview evaluateJavaScript:@"app.onFaceRealName('uid11292803112345946uuid')" completionHandler:^(id _Nullable result, NSError * _Nullable error) {}];

結(jié)論：

1.傳給值如果是數(shù)字的字符串，加不加單引號(hào)都可以

2.傳值如果是有其他字符的字符串，必須加單引號(hào)
